Embodiment 1

[0058] A train control system suitable for retrofitting existing lines, including ground equipment and on-board equipment. Among them, the ground equipment such as Figure 1a shown, including, interlocking system, parallel port LEU, and active transponder installed at the station and connected in sequence. The interlocking system can be a computer interlocking system or a relay interlocking system, both of which have an execution relay group, and the parallel port LEU can be connected to the execution relay group through the parallel port I / O (input / output). The parallel port LEU collects the contact status of the interlocking system from the parallel port I / O, and combines the contact status of the interlocking system into an entry selection condition (it can be considered that the combination relationship of the contact status of the relevant switch representing the relay group represents the entry route selection condition), send the station message stored in the parallel p...

Embodiment 2

[0076] During construction along the railway line, it is necessary to temporarily limit the speed of trains passing through the railway in the construction section to ensure the safety of construction personnel and trains. How to safely set a temporary speed limit is a difficult problem in a transportation line not exceeding 160km / h. The existing in-vehicle system of the existing line is set up through the IC card, and the temporary speed limit information is prepared in advance, and then burned into the IC card. Insert the vehicle control system interface (generally set on the DMI), and import the data into the control system (LKJ for the C0 system). Usually a large construction plan is a monthly plan, such as submitting the construction plan for the next month in the middle of each month; in actual implementation, it can be required to report the construction plan for the next week every week to determine the temporary speed limit. The temporary speed limit information for ...

Embodiment 3

[0086] As a more optimized solution of the second embodiment, the updated temporary speed limit information is sent to the in-vehicle device only when the temporary speed limit information is updated.

[0087] Specifically as Figure 1b As shown, a "temporary speed limit message update button" is set at the station to select the "updated" state and "not updated" state of the "temporary speed limit message update" status bit. It can be considered that these two states are represented by a binary "temporary rate limit message update" status bit, for example, "0" represents the "unupdated" state, and "1" represents the "updated" state. The "temporary speed limit message update button" can be pressed by the station attendant when the temporary speed limit information is updated.

[0088] The initial status bit of "temporary speed limit message update" is "not updated"; when the temporary speed limit server updates the temporary speed limit message, the station attendant can press...

Abstract

The invention discloses a train control system adapting to existing line reconstruction. The train control system adapting to existing line reconstruction comprises ground equipment and on-board equipment. The ground equipment comprises an interlocking system, a parallel-port LEU and an active balise which are mounted in a station and connected sequentially, wherein the parallel-port LEU combines contact states of the interlocking system into access selection conditions and sends station messages to the corresponding active balise, and when a train passes through an acting range of the active balise, the active balise sends the corresponding station message to the on-board equipment of the train. The on-board equipment comprises a BTM (balise transmission module), a BTM antenna and an automatic train protection system, wherein when the train passes through the acting range of the active balise, the BTM receives the station messages sent by the active balise and sends the station messages to the automatic train protection system for subsequent processing. The train control system adapting to existing line reconstruction has the advantage that access information is sent to the on-board BTM through the station messages to enable a driver to acquire correct access information directly, so that the train pull-in risk that the driver selects wrong access information due to misoperation is avoided.

Description

technical field [0001] The invention relates to the field of train control in the railway industry, in particular to the field of train operation control systems and methods suitable for the reconstruction of existing lines. Background technique [0002] With the continuous improvement of the national economy's requirements for railway transportation, the requirements for railway train operation management and safety control are also constantly upgraded. The China Train Operation Control System (CTCS) is divided into different levels according to the train speed and the demands of railway operation. Among them, my country's main railway lines (existing railway lines) are CTCS-0 (referred to as C0), and the train running speed is below 160km / h. Circuits, interlocks and automatic blocking devices are used as ground equipment. In the C0 system, when the train is running, it relies too much on the driver's operation, which is labor-intensive, and the most important thing is low...
